Abstract (en)
[origin: WO2015021286A2] A centrifugal separator recovers high specific gravity solids such as whole cells while at the same time enabling sedimentation of low specific gravity solids such as cell debris. The separator is provided with a dual zone separator liner with concentric separator shells or zones. Feed fluid is introduced into an inner shell. High specific gravity solids accumulate against the inner wall of the inner shell. Feed fluid flows into the coaxial outer shell where lower specific gravity solids accumulate on the inner wall of the outer shell under higher g-force relative to that within the inner shell for the same rotational speed. Feed fluid flows out an exit channel. Longitudinal, planar vanes are radially disposed between an outer shell inner wall and an inner shell outer wall. After centrifugation, feed fluid in the inner shell is drained, then accumulated solids are drained from the inner shell into an appropriate receptacle.
